Which term indicates a position farther from the median plane?

The term that indicates a position farther from the median plane is "lateral." In anatomical terminology, the median plane refers to an imaginary line that divides the body into equal left and right halves. When a structure is described as lateral, it means that it is situated to the side of or farther away from this central line compared to another structure.

For instance, when comparing the arms to the torso, the arms are lateral to the median plane because they are positioned further away from this dividing line. This concept is fundamental in anatomy as it helps define the relative positioning of body parts.

In contrast, the terms medial, proximal, and supine do not accurately convey the idea of being farther from the median plane. Medial refers to something that is closer to the median plane, proximal relates to being nearer to the point of attachment or origin compared to another structure, and supine describes a body position lying face up rather than a spatial relationship to the median plane. Understanding these directional terms is crucial for effective communication in a medical context.
